Appearance
Enoplometopus occidentalis is easily identifiable due to its striking neon red or orange body, accompanied with distinctive white marking, and yellow hair-like structures. Its first pair of legs has slender, elongated claws and adult males can grow up to 14 cm (5.5 in) in length. The smooth, rounded abdominal leads to a rounded tail with a central spine and three movable side spines. In males, the first swimming limb looks leaf-like, while in females, it appears thread-like; the first pair of these limbs are modified for reproduction.
